[0027] The present utility model will be further described below in conjunction with the drawings and embodiments

[0028] First embodiment

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , wherein Figure 1 Schematic diagram of the structure of the first embodiment of a new energy-saving digital display electric hot plate for experiment and assay heating provided by the present utility model Figure 2 is Figure 1 Schematic diagram of the structure from another perspective shown Figure 3 is Figure 1 Schematic diagram of the cross-sectional structure of the outer shell shown. A new energy-saving digital display electric hot plate for experiment and assay heating includes: base 1

[0030] Weight sensor 6, the bottom of the weight sensor 6 is fixedly installed on the top of the base 1

[0031] Outer shell 3, the bottom of the outer shell 3 is fixedly installed on the top of the weight sensor 6, and a heat conduction plate 32 is fixedly installed inside the top of the outer shell 3, and a heating element 33 is fixedly installed at the bottom of the heat conduction plate 32

[0032] Control box 5 is provided on one side of the base 1. On the top of the control box 5, there are respectively a display screen 51, a temperature adjustment knob 52 and a weight adjustment key 53. The display screen 51 is electrically connected to the weight sensor 6 and the heating element 33 respectively. The temperature adjustment knob 52 is electrically connected to the heating element 33. The weight adjustment key 53 is electrically connected to the weight sensor 6.

[0033] Inside the control box 5, there is a heating switch which is used to control the switch of the heating element 33 and is also electrically connected to the weight sensor 6.

[0034] After presetting how much the weight is reduced through the weight adjustment key 53, the heating switch controls the heating element 33 to turn off.

[0035] Rubber pads 11 are fixedly installed around the bottom of the base 1. Fixing rods 2 are fixedly installed around the top of the base 1. Inside the top of the fixing rod 2, an extension rod 21 is slidably connected. The top of the extension rod 21 is fixedly installed at the bottom of the outer shell 3.

[0036] By installing the rubber pads 11 around the bottom of the base 1, when in use, it can play an anti-slip role. By installing the fixing rods 2 and the extension rods 21 on the top of the base 1, it can play a role in limiting the outer shell 3.

[0037] A surrounding plate 4 is fixedly installed on the top of the outer shell 3. The surrounding plate 4 is arranged on the outer side of the heat conduction plate 32.

[0038] A heat reflection plate 31 is fixedly installed on the inner side of the outer shell 3.

[0039] The heating element 33 is preset to a temperature of 150 °C and is in the on state. After the spodumene / lepidolite pulp after flotation is completed in the laboratory, it is filled in a stainless-steel basin and placed on the heating element 33 for drying. After the weight sensor 6 is installed under the heating element 33 board, it will sense that there is a sample on the heating element 33 that needs to be heated, and it will trigger the heating switch to start heating and drying. When the spodumene / lepidolite slurry is dried, the tray is removed, and the weight sensor 6 on the heating element 33 will sense that there is no sample on the heating element 33, and the heating switch will turn off.

[0040] The ordinary heating element 33 is preset to a temperature of 150 °C and is in the on state and continues to heat. After the slurry sample is placed, it starts to heat, and it remains in the heating state after the sample is removed.

[0041] The heating element 33 is pre-set to a temperature of 100 °C. The potassium chloride and sodium chloride solutions can be evaporated and concentrated. After pre-setting the weight change on the weight sensor 6, heating can be stopped. For example, for a 100 ml solution of potassium chloride and sodium chloride, 30 g of water needs to be evaporated. Set the gravity difference on the heating element 33 and the weight sensor 6. When 30 g of water has evaporated, the weight sensor 6 will sense the weight change and then immediately stop heating.

[0042] The heating element 33 is pre-set to a temperature of 180 °C. When the laboratory needs to dissolve samples irregularly for testing, the samples to be dissolved are placed on the heating element 33 for heating and dissolution. The weight sensor 6 on the heating element 33 will detect the presence of the sample and start the heating switch for heating. When the sample dissolution is complete, the tester removes the dissolved sample, and the weight sensor 6 will sense that there is no sample on the heating element 33 and then stop heating.

[0043] The working principle of a new energy-saving digital display electric hot plate for experiment and chemical analysis provided by the present utility model is as follows:

[0044] When in use, the user first powers on the control box 5, and then adjusts the temperature of the heating element 33 through the temperature adjustment knob 53. The adjusted temperature value will be displayed on the display screen 51. Then, the material to be heated is placed on the inner side of the tray, and then the tray is placed on the top of the heat conduction plate 32. At this time, the weight sensor 6 senses the weight and displays the weighed value on the display screen 51. At this time, power is supplied to the heating element 33 through the control box 5, so that the heating element 33 is heated to the adjusted temperature to heat the material inside the tray. When the heating is over, the user removes the tray from the top of the heat conduction plate 32. At this time, when the weight sensor 6 senses that the weight on the top of the outer shell 3 is zero, the control box 5 will stop supplying power to the heating element 33, thus stopping heating.

[0045] Compared with the related technology, a new energy-saving digital display electric hot plate for experiment and chemical analysis provided by the present utility model has the following beneficial effects:

[0046] Through the cooperation of structures such as the base 1, the weight sensor 6, the control box 5, the temperature adjustment knob 52, the weight adjustment key 53, and the heating element 33, when in use, the weight sensor 6 monitors the weight on the outer shell 3. When the weight on the top of the outer shell 3 is zero, the heating element 33 can be automatically turned off, which can avoid the situation that the heating element 33 is forgotten to be turned off by the staff after use, making the device more energy-saving and environmentally friendly.

The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0050] A magnetic plate 75 is fixedly installed at the top of the inner side surface of the sliding cavity 73, and a metal plate 74 is fixedly installed at the bottom of the protection frame 71.

[0051] A moving plate 72 is fixedly installed at the top of the protection frame 71, and the moving plate 72 is arranged on the top of the bottom frame 7.

[0052] The working principle of a new energy-saving digital display electric hot plate for experiment and chemical analysis heating provided by the present utility model is as follows:

[0053] When placing materials on the heat conduction plate 32 for heating, the user can move the moving plate 72 upward, so that the moving plate 72 drives the protection frame 71 to move upward, so that the protection frame 71 moves out from the inner side surface of the sliding cavity 73 and surrounds the outer side surface of the housing 3. At this time, the metal plate 74 and the magnetic plate 75 are magnetically attracted, so as to be able to limit the position of the protection frame 71.

[0054] Compared with the related technology, a new energy-saving digital display electric hot plate for experiment and chemical analysis heating provided by the present utility model has the following beneficial effects:

[0055] Through the cooperation of structures such as the bottom frame 7, the protection frame 71, the moving plate 72, the sliding cavity 73, the metal plate 74 and the magnetic plate 75, when heating materials, the protection frame 71 can be moved upward, so that the protection frame 71 covers the outer side surface of the heated materials, thus playing a protective role, avoiding accidental touch by staff and increasing safety.
